Death and disease attributable to fine particle pollution from Marshall Plant
In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants.[1] Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.[2]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 130 | $960,000,000 |
| Heart attacks | 200 | $22,000,000 |
| Asthma attacks | 2,200 | $110,000 |
| Hospital admissions | 98 | $2,300,000 |
| Chronic bronchitis | 80 | $36,000,000 |
| Asthma ER visits | 120 | $43,000 |

Renewal plant permit approved, with modifications
On Jan. 18, 2011, renewal permits for Duke Energy's Marshall Steam Station, Riverbend Steam Station, and G.G. Allen Steam Plant were approved by the North Carolina Department of Environment and Natural Resources division of water quality. Riverbend and Allen steam stations in Gaston County.The National Pollution Discharge Elimination System permits were renewed with some changes for the coal-fired power facilities that allow the discharge of treated wastewater to the Catawba River Basin, according to information from the state Department of Environment and Natural Resources.[3]
According to the department, the changes include:[3]
- Quarterly monitoring for mercury was added to outfall from the coal ash ponds at the Riverbend Steam Station. This will establish a monitoring plan for mercury, selenium and arsenic that is consistent for all three permits.
- Fish tissue monitoring, at least once per permit cycle, has been added to all three permits.
- Semi-annual in-stream monitoring was added for arsenic, selenium, mercury, chromium, lead, cadmium, copper, zinc and total dissolved solids. The monitoring is to occur upstream and downstream of ash pond outfalls at all three facilities.
- Liquid coal ash storage structures shall meet the dam design and safety requirements according to the state administrative code.
The permits also require Duke to install groundwater monitoring wells and to comply with groundwater standards, according to information from the state. While the permits require monitoring, the state didn’t go far enough, according to Catawba Riverkeeper David Merryman: “It’s disturbing to me that the state is allowing the unlimited release of mercury, selenium and arsenic into our waters." Merryman said he plans to look into the option of appealing the state’s decision on the permits.[3]
Citizen action
May 3, 2012: Activists block shipment of mountaintop removal coal
On May 3, activists protested mountaintop removal mining by locking themselves to train tracks, preventing coal train loads from entering Duke Energy's Marshall Steam Station in North Carolina. The activists, affiliated with RAMPS, Katuah Earth First!, Greenpeace and Mountain Keepers said they would not leave until Duke agreed to end its use of mountaintop removal coal operations. The power burned in Marshall is used to power Apple's iCloud data center.[4]
Coal Waste Site
"High Hazard" Surface Impoundment
Marshall Steam Station's Active Ash Pond is on the EPA's official June 2009 list of Coal Combustion Residue (CCR) Surface Impoundments with High Hazard Potential Ratings. The rating applies to sites at which a dam failure would most likely cause loss of human life, but does not assess of the likelihood of such an event.[5]
